These are instructions on how to downgrade the firmware of your iPhone 4s using RedSn0w for Mac.

In order to continue you will need to have SHSH Blobs saved for the lower firmware version you are downgrading to. You can use RedSn0w or TinyUmbrella to save your SHSH blobs. Also make sure you have performed a backup of your device using iTunes.

You may want to do this to downgrade from iOS 5.1.x to iOS 5.0.1 for jailbreak.

Step OneCreate a folder called Pwnage on your desktop and download the following items into the folder.- The latest version of RedSn0w- The current iOS firmware (iOS 5.1.1)- The older firmware you want to downgrade to (iOS 5.0.1)

Double click the RedSn0w archive to extract it.

Step TwoLaunch the RedSn0w application from the extracted RedSn0w folder.

Step ThreeSelect Extras from the main menu.

Step FourChoose Even More from the extras menu.

Step FiveSelect Restore from the even more menu.

Step SixClick the IPSW button.

Step SevenNavigate to the Pwnage folder on your desktop and choose the firmware ipsw you would like to restore to and click Open.

Step EightYou will be informed that an additional IPSW is required. Make note of the ipsw file requested and click the OK button.

Step NineSelect the additional ipsw specified in the previous step and click the Open button. (This will likely be the most current firmware ipsw).

Step TenYou will be warned that if you continue your baseband will be updated to the latest version. If you want the best chances of unlocking your phone in the future you should not continue. If you do not care about an unlock click the YES button.

Step ElevenYou will now be informed that your device will be placed into recovery mode. Click the OK button.

Step TwelveYou must now select your blobs for restore. You can choose to specify local blobs or remote blobs.

REMOTE BLOBS- Choose this option if you previously saved your blobs with RedSn0w and they were stored on the Cydia server. This is the easiest option if it's available to you.

LOCAL BLOBS- Choose this option if you previously saved your blobs with TinyUmbrella or you used RedSn0w but did not let Cydia save a copy of your blobs.- After clicking Local you will be prompted to select your saved blob file for the firmware you are downgrading to. If you used TinyUmbrella, simply press COMMAND+SHIFT+G, input ~/.shsh, and clickGo to navigate to the folder with your saved SHSH blobs. Select the file that matches the ECID displayed in RedSn0w and the firmware version you are downgrading to, then click Open.

Step TwelveRedSn0w will now stitch your blobs to the firmware ipsw and automatically begin a restore to the modified firmware.

Step ThirteenYou will be informed that your restore has been successful! If you were downgrading to jailbreak you can find jailbreak instructions here.

The iPhone Dev-Team has released a new version of RedSn0w that can downgrade the iPhone 4S and iPad 2/3 for those with saved SHSH blobs.

Starting with redsn0w version 0.9.11b1, those with newer devices (iPad2, iPad3, and iPhone4S) can join the downgrade fun too! In a radical departure from previous versions of redsn0w, it now directly supports restoring IPSWs to your device. The first use of this new feature implements a hack that allows A5 downgrades without a bootrom-level exploit.

Some important points:● The new feature is at Extras->Even More->Restore● You cannot downgrade without the personalized SHSH blobs for your device at that lower firmware. You need to have fetched those blobs while the signing window was open, using either Cydia's built-in TSS@Home feature, or with TinyUmbrella. The new Restore screen of redsn0w lets you choose either the remote blobs or local ones (for the earlier firmware). If you don't know where TinyUmbrella put your blobs, TinyUmbrella has a button that will show you (copy them out of that folder and feed them to redsn0w).● he A5 downgrade method actually updates to the latest firmware before downgrading to the earlier one. This process updates your baseband to whatever is newest. DO NOT USE THIS METHOD IF YOU RELY ON UNOFFICIAL UNLOCKS of your iPhone4S. Those who used the temporary SAM technique to unlock their iPhones to specific SIMs shouldn't be affected by this baseband update.● This method can be fixed by Apple with a firmware update. It's a (pleasant) mystery why they haven't fixed it yet, because reverse-engineering of the restore ramdisk indicates they do know about it. It's possibly too niche to bother to fix right now.● The least-tested devices with this method are the iPad2,3 and iPad3,2 (because we don't have those models). If you do and you feel like experimenting, please let us know how it turns out in the comment section below!● This update involves a bunch of new redsn0w code. We recommend sticking to the previous version 0.9.10b8b unless you're specifically using this new feature, until all the bugs are worked out! (Note: If redsn0w gets stuck at the "Waiting for device" stage for more than 30 seconds, you've hit a pesky GUI bug... that will be fixed in an upcoming version!)

You can download the latest version of RedSn0w from here. We will be posting a tutorial on how to perform the downgrade shortly!
